Hello,
My script works but I keep getting one of the following 2 frustrating errors:
1- Use of uninitialized value in string eq...
2- Use of uninitialized value in concatenation (.) or string...
The error occurs the fourth time the subroutine is called. According to
perl.com, the error means - "This means that you're trying to use a variable
before you've assigned a value to it" I think the problem may be in the code
snippet below, could it that $_[0] needs to be reinitialized? If so, how?
my array = ("", "Y", "N");
function($scalar_value1);
sub function {
my ($value, $item, $selected);
$value = $_[0]; #$_[0] should eq first (and only) value of
$scalar_value1
foreach $item(@array) {
if ($item eq $value){
$selected = "selected";
}
print "<option value=\"$item\" $selected>$item</option>\n";
}
}
